im having a little trouble with my nuclear equation chemistry homework. These are the 2 problems:
beta decay of 165,61Pm and beta decay of 152,54Xe. I'm pretty sure the answers are: Pm--->0,-1B+165,62Sm and Xe---->0,-1B+152,55Cs. Please help!

Beta decay results in the emission of an electron, which keeps the mass number the same but increases the atomic number by 1, so you move one element up in the table.
So, Pm-165 would beta decay to Sm-165 and Xe-152 would decay to Cs-152. You have them correct.

using notation like 228/90 Th for thorium 228 228/90 Th ---> 224/88 Ra + 4/2 He2+ 224/88 Ra ---> 220/86 Rn + 4/2 He2+ 220/86 Rn ---> 216/84 Po + 4/2 He2+ 216/84 Po ---> 212/82 Pb + 4/2 He2+
